Problems solved by technology

[0002] In the traditional calcium carbide clear liquid circulating cooling system, most of the cooling towers used are non-filler spray cooling towers. During operation, calcium carbide clear liquid is very easy to scale on the atomizing nozzles, delivery pipes and water eliminators, resulting in atomizing nozzles, The conveying pipe and water eliminator are blocked, which cannot achieve the ideal atomization cooling effect, and the cooling water volume and cooling air volume are greatly reduced, and the floating water is serious, causing pollution and corrosion to the surrounding working environment and equipment, and the atomization needs to be disassembled every month Pickling and descaling of nozzles and pipelines has seriously affected production safety and is a common problem in the calcium carbide acetylene industry
